Answer 1

a)6/7·1½:1⅓ =6/7 · 3/2 : 4/3 =9/7 · 3/4 =27/28

 

b)1³/₈ :3/4 :1²/₉ = 11/8 :3/4 : 11/9=11/8·4/3 :11/9=11/6 ·9/11=9/6=1³/₆=1½

 

c)1⁵/₆:3 ⅔·1 ¹/₇=11/6 :11/3 ·8/7 =11/6· 3/11 · 8/7 =1/2 ·8/7 =8/14=4/7

 

d)(½)³·2⅔ :1¹/₆ =¹/₈ · 8/3 : 7/6 =1/3 · 6/7 =2/7

 

e)1¼·6 -3 :1¹/₅ =5/4 ·6 -3: 6/5 =30/4 - 3· 5/6 =15/2  - 5/2  =10/2=5

 

f)(4³/₈-1⅔):3 ¾=(35/8 -5/3):15/4 =(105/24 -40/24)· 4/15 =65/24 ·4/15=13/18

 

g)2¹/₅ -1¹/₆ :2⅓ =11/5 -7/6 :7/3 =11/5-7/6 · 3/7 =11/5 -1/2 =22/10-5/10=17/10

 

h)[(³/₈+¹/₆):3¼]-(⅓)³ =[(9/24 +4/24) :13/4 ] - 1/27 =[13/24 ·4/13] -1/27=

1/6 -1/27 =9/54  - 2/54 =7/54
